The Hidden Crisis Behind a Bad Smell: Homelessness, Empathy, and Practical Advice

There’s a thread going around that caught my eye this week, and it’s one of those situations where the practical problem on the surface gives way to something much bigger underneath. Someone came home to find two unhoused men had sheltered in the small vestibule of their apartment overnight. The men left without incident, but the smell they left behind has been absolutely brutal — weeks of trying various cleaning methods and nothing has shifted it.

Reading through the discussion, most people were genuinely helpful. Someone made a really solid point that vinegar, despite being the internet’s favourite cure-all, is not a disinfectant. It won’t reliably kill off heavy bacterial colonies that are the actual source of that kind of persistent odour. The real culprits are likely the floor mat and the floor itself — porous surfaces that absorb biological matter and just keep generating the smell. Enzyme-based cleaners seem to be the consensus winner here, products like Nature’s Miracle or similar enzymatic cleaners that actually break down the organic compounds rather than just masking them. A few people also flagged that misting bleach indoors isn’t a great idea, and mixing it with vinegar is genuinely dangerous — please don’t do that one.

One person even suggested an ozone generator, then promptly walked it back when they realised it was a shared vestibule space. Good catch, because ozone is no joke — it’s a powerful oxidiser that can seriously damage lungs. With cats in the picture too, that’s definitely one to approach with extreme caution or skip entirely.

But here’s where my mind kept drifting as I read through all of this.

The person posting is clearly distressed — it took them two days to work up the courage to go back into that space and remove the clothing. Two days. That tells you something about the psychological weight of having your home, your sense of safety and sanctuary, breached like that. And I get it. Truly. Your home is supposed to be the one place where you feel completely secure.

At the same time, I kept thinking about those two men. On a cold night, they found an unlocked door and took shelter. They left without causing any trouble. No confrontation, no damage beyond the smell. They were just… surviving. And now they’re out there somewhere, probably finding another doorway, another vestibule, another brief reprieve from whatever brought them to that point in their lives.

We have a significant rough sleeping problem in Melbourne. You see it around Flinders Street, along the Yarra, in CBD laneways. It’s easy to walk past and tune it out, especially when you’re rushing to catch a tram or grab a takeaway coffee. But every now and then something pulls you up short and makes you actually see it.

What struck me in the comments was one person gently noting the smell might partly be a stress response — a psychosomatic element layered on top of the real smell — because the person had been violated. That’s not an unreasonable observation. Trauma does weird things to our senses and perceptions. But several others quite rightly pushed back on the idea that it was all in her head, particularly since other visitors to the apartment confirmed the smell independently. Bodies in distress — through illness, poor nutrition, lack of access to sanitation — can produce smells that genuinely cling to surfaces for weeks. That’s not a judgement on the people involved; it’s just biology meeting poverty.

There’s an uncomfortable tension in this whole situation that I think a lot of us navigate. You can simultaneously feel compassion for people experiencing homelessness and feel distressed that your personal space was entered without consent. Those two things don’t cancel each other out. The problem isn’t the individuals — it’s a system that leaves people with nowhere safe to sleep, no access to showers or sanitation, and no real path out of crisis without navigating an overwhelmed and underfunded support network.

The OP mentioned they’re in Chicago, which has its own serious homelessness challenges. But honestly, swap that for Sydney or Melbourne and the story barely changes. We’re not doing nearly enough, and the gap between political rhetoric about “cleaning up the streets” and actual investment in housing and mental health support remains embarrassingly wide.

Anyway — practical takeaways for anyone who finds themselves in a similar situation: enzymatic cleaners are your friend, get that floor mat out immediately, clean the actual floor with proper soap and water before applying anything else, and make sure you’re actually hitting the most contaminated surfaces rather than just spraying things at random. And please, don’t mix bleach and vinegar. Your lungs will not thank you.

The bigger problem, though? That one’s going to take a lot more than an enzyme spray to fix.
